If you get the paperpack version, turn to page 146 and prepare to laugh and be amazed. Ackerman recounts the story of Throckmorton, an African Grey Parrot whose verbal ability is astonishing.
Throckmorton belongs to a couple, Karen and Bob, and his housemate is a miniature schnauzer.
Throckmorton perfectly mimics the ring tone of Bob's cell phone. Then he mimics Bob answering it, "Hello? Uh huh, uh huh, uh huh." Then Throckmorton mimics the sound of Bob hanging up. From the other room, Karen thinks (knows) that Bob is in the next room and has been talking on the phone.
Throckmorton's cell phone fluency is a great way to entertain himself, getting Bob and Karen both running, looking for their phones.
When Throckmorton wants some action, he mimics the schnauzer barking as if someone has knocked on the door. The schnauzer then joins, wondering, no doubt, how he missed the door knocker. No one, including Bob and Karen, can tell the difference between the parrot barking and the dog barking. Karen says that Throckmorton makes their house sound like a kennel.
When Bob has a cold, Throckmorton does his nose-blowing, coughing, and sneezing routine, exactly like Bob. Throckmorton mimics the sound of Bob slurping his coffee. He can do a perfect rendition of Karen gulping water.
And of course, Throckmorton has a comprehensive command of English, including those colorful words that can make certain dinner guests uncomfortable.
Further, he perfectly mimics both Karen's and Bob's voices. So if he wants someone to come, he calls out, "Bob" in Karen's voice, or "Karen" in Bob's voice.
Never a dull moment in Throckmorton's house!
I highly recommend Ackerman's book.
